Optically active nanomaterials have been extensively developed in the last two decades for their potential applications in the field of sensing and biosensing, imaging, drug delivery, fabricating optoelectronic devices, disease diagnosis, and monitoring, etc., because of their unique and superior optical properties over the organic dyed variety. In the field of sensing and biosensing, nanomaterials such as SPR active noble metal nanoparticles, fluorescent metal nanoclusters, semiconductor QDs, carbon nanomaterials, metal oxides etc., are widely utilized for the designing of sensing probes. This book aims to critically summarize the potential sensing applications of optically (chromogenic and fluorogenic) active, nano-sized organic and inorganic materials for the selective detection of ionic analytes (such as metal ions and anions), in various environmental and biological samples. A thorough discussion will be had on the design, synthesis, sensing mechanisms, and applications for detecting ionic analytes. Each chapter deals with the sensing applications of one kind of nanomaterial. This book is an important reference source for materials scientists and engineers seeking to increase their understanding of how nanomaterials are being used for sensing applications. Provides information on the various types of optically active inorganic and organic nanomaterials including quantum dots, SPR active noble metal nanoparticles, metal nanoclusters, organic nanoparticles and carbon dotsSummarize the synthesis, design, and development of the sensors along with their mechanismsExplains major sensing applications and manufacturing challenges
